+Read a line of data from the file in tsv (i.e. '0.3  0.55    0.56    ' is a vector of 3 values) and creates a channel (a vector) containing these data.
+If there are many lines, it updates the data as fast as possible with each time.
+It is very fast you can be either be synchronized or using -p to requiert a minimal time between each update.
+You can also use a first column describing the time in µs to read the line.
+Finaly you can limit the number of line read by using -n.

+You can specify the frequency with -f and the refresh rate with -r.
+The refresh rate defines how often you will update the value of the oscillator but will not change the frequency.

+You can use a buffer to keep the historic of the oscillation.
